No problem here, I just need to know what to tweak I need to get past this when I click my audio player's download button:

This link is simulating an RFI hacking URL that is why BPS is blocking it.

RFI URL pattern: http:...hackerfile=http:...

You will need to create a skip/bypass rule for this plugin. This skip/bypass rule will go above skip/bypass rule #12 in your root htaccess file. You can also add this skip/bypass rule to BPS Custom Code so that it is saved permanently.
